Now we're getting somewhere. My particular ISP does not supply me with an 
entire hierarchy of newsgroups that my for-pay NNTP server does. Still 
think I'm making a bad choice?

There's no mystery here. Clearly (according to their own message, they are 
blocking on a range of addresses that are not known to be spammers. 

A possible solution to their problem is to segregate out a seperate server 
for mailinglists from the rest of the mail used by the company. Clearly 
everyone agrees that the lists themselves only allow mail from 
subscribers, so no RBLs are needed for that (possible) subdomain.

Failover has to do with reception, not transmission.

See the MX record for syslang.net. I'm primary and my DNS provider is 
secondary.

I still want to try and make it better. Hope you're not too badly 
offended.
